Did JLR change the pulley size or orientation for the 16MY F-Type R? I bought an SC drive belt from FCP Euro (Continental part 8DK1412, listed as JLR part C2D39175), but I can't for the life of me get it over the pulleys. The old belt came off pretty easy, and then I spent an hour trying to get the new one over the pulleys without prying it, and it's clearly just too short. I can get it over all but one of the pulleys, and it just won't go. Put the old belt back on and it went on just as easy as it came off, and the tensioner only moves back a couple inches under load, so it's not all that loose. When I google the Continental part number some sites show the fitment goes on any 3.0 or 5.0 current-gen AJ motor, and some show it only goes through '15 F-Types. Did FCP Euro send the wrong belt?

 

Call the dealer with your VIN. I was chasing an A/C belt on a CTS-V this week and Worldpac had it wrong. Wound up getting the superseded number from a Chevy dealer.

 

So apparently there's two different SC drive belts that were used on a bunch of models, I guess they used different pulley combinations that changed the belt length, even within the same model year and trim of the production run. When I used my VIN on a JLR parts fiche, both belts pull up as direct fitments, but they're two different lengths. To make it worse, the diagram image for one of the belts is the SC belt routed in the installed configuration around the idlers, crank, SC, and tensioner pulleys, but without those pulleys depicted. The other one is a diagram of the idler and tensioner pulleys themselves, with no belt depicted, but the description on both says it's the SC drive belt itself that the P/N corresponds to. I started a return on the belt I have and put the other one on order. I was really looking for the actual Continental part number so I didn't have to pay $80 to JLR for a $20 belt, but it is what it is. lol If the new belt comes in OEM Conti packaging I'll update this thread with the two Continental part numbers, hopefully it'll help someone else.
